CN201300231Y - Lathe tool-rest auger drill socket - Google Patents

Abstract

The utility model relates to the machinery-processing field, in particular to a lathe tool-rest auger drill socket, which solves the problems that drill holes employ the manual operation on the prior lathe, the time-consuming and labor-consuming characteristics are provided, the worker labor intensity is large, and the production efficiency is low and the like. A conical hole and a square hole which are engaged with a drill head are opened on a drill socket body, an armature is arranged in the square hole, one side of the drill socket body has a connecting block which is engaged with a tool-holding groove on a lathe tool-rest along the axial direction of the conical hole, the distance of height between the axial-center of the conical hole and a connecting block is equal to the height of a lathe main shaft, and the connecting block is integrated with the drill socket body to form one body. An axial automatic feed mechanism on the lathe is fully used to enable the drill socket and the drill head to freely move, which achieves automatic hole-drilling, lowers the worker labor intensity, enhances the production efficiency, avoids the unstable cutting to break the drill head due to reasons like different large or small force and discontinuous cutting when workers drill holes, can effectively control the depth of holes, and reduces errors.

Description

Lathe saddle fluted drill drill bushing

Technical field

The utility model relates to field of machining, is specially a kind of lathe saddle fluted drill drill bushing.

Background technology

Known, fluted drill is a kind of aperture knife tool of use amount maximum, and it is mainly used in boring, also can be used to reaming.Boring still is to carry out according to the conventional method on lathe at present, specifically be that the fluted drill drill bit is contained on the tail stock by drill bushing, workpiece is installed on the rotatable scroll chuck, adopt manually-operated boring then, the method operates very inconvenient, time-consuming effort again, the labor strength height, production efficiency is very low.Prior problem is that the advantage of lathe is not fully used, and this is because lathe itself has the knife rest of automatic feed mechanism control, but on original knife rest the suitable drill bushing that drill bit is installed is not set.

Summary of the invention

The utility model adopts manually-operated in order to solve on the existing lathe boring, has problem such as waste time and energy, labor strength is big and production efficiency is low, and a kind of lathe saddle fluted drill drill bushing is provided.

The utility model is to adopt following technical scheme to realize: lathe saddle fluted drill drill bushing, have on the drill bushing body and the round taper hole of drill bit coupling and the square opening that is communicated with round taper hole one end, innovative point of the present utility model is that this drill bushing body one side is provided with along round taper hole axis direction and the contiguous block that cooperates with knife holder slot on the lathe saddle, and the round taper hole distance of shaft centers is contour from the height and the lathe spindle of contiguous block bottom surface.When on lathe, holing, employed drill bit is packed in the drill bushing of structure described in the utility model, in the knife holder slot of contiguous block clamping on knife rest of drill bushing, at this moment the center of drill bushing high naturally with regard to and the lathe spindle center contour, then workpiece is fixed on the scroll chuck, after utilizing the middle carriage centering alignment of shafts and bit central to overlap, can make a mark at the saddle of lathe and the same place of middle carriage, so, no matter whenever hole, as long as big, mark on the middle carriage when overlapping, error is just very little, just adjusting slightly can very fast centering, according to drill bit size, select suitable cutting data, the sufficient cutting fluid of annotating, so just can utilize lathe spindle to drive knife rest to automatic feed mechanism moves, thereby drive drill bushing and drill bit workpiece is holed, process one after, use the lathe quick mechanism to withdraw from drill bit, next workpiece of clamping does not need centering once more then.

The utility model cooperates the higher contiguous block of positioning accuracy having increased on the structure of original drill bushing with knife holder slot on the knife rest, made full use of the axial automatic feed mechanism on the lathe, make drill bushing and drill bit axially to move freely, realize automatic drilling, compared with prior art, have the following advantages:

(1) can select rational cutting data according to the size and the workpiece material to be processed of drill bit;

(2) saved all muscle power of the artificial boring of employing, greatly reduced labor strength, production efficiency improves greatly;

(3) utilize lathe spindle to the auto-feed structure decrease withdraw from non-cutting times such as drill bit and idle stroke;

(4) after selecting suitable cutting data, the feeding process is more steady, varies in size because of strength when having avoided artificial boring, is interrupted reason such as cutting and causes working angles not steady, and drill bit is fractureed;

(5) degree of depth of the effective control hole of energy reduces error;

In a word, the utility model improves simple in structure, reasonable in design, easy to use, has realized lathe automatic drilling function, has certain popularization value.

Fig. 3 is a left view of the present utility model

Among the figure: 1-round taper hole 2-square opening 3-contiguous block 4-drill bushing body

The specific embodiment

Lathe saddle fluted drill drill bushing, as shown in Figure 1, 2, 3, have on the drill bushing body 4 and the round taper hole 1 of drill bit coupling and the square opening 2 that is communicated with round taper hole 1 one ends, when the dismounting drill bit, in square opening 2, insert armature, this drill bushing body one side is provided with along round taper hole 1 axis direction and the contiguous block 3 that cooperates with knife holder slot on the lathe saddle, and round taper hole 1 distance of shaft centers is contour from the height and the lathe spindle of contiguous block 3 bottom surfaces.Convenient for processing and fabricating, improve mechanical strength, contiguous block 3 is made one with drill bushing body 4, and contiguous block can be square entity, also can be hollow.

In boring procedure, the radial center that observe drill bit whether with the lathe spindle dead in line, if any error, in time adjust, the amount of feeding can not be excessive when just beginning to cut, and waits drill bit to pierce behind the workpiece conversion amount of feeding again.Drill bushing structure of the present utility model can be widely used in the lathe of models such as CA6140, CA6163, CA6180, and the concrete size of drill bushing can determine according to the model of lathe, guarantees the drill bushing clamping after on the knife rest, and the center is high to get final product with the lathe spindle center is contour.

Claims (2)

1, a kind of lathe saddle fluted drill drill bushing, have on the drill bushing body (4) and the round taper hole (1) of drill bit coupling and the square opening (2) that is communicated with round taper hole (1) one end, it is characterized in that this drill bushing body one side is provided with along round taper hole (1) axis direction and the contiguous block (3) that cooperates with knife holder slot on the lathe saddle, round taper hole (1) distance of shaft centers is contour from the height and the lathe spindle of contiguous block (3) bottom surface.
